Plot: “A fast-talking fox, named Nick Wilde, lives in the animal city of Zootopia, divided in neighborhoods like Tundratown, Sahara Square, Little Rodenta, and Burrowborough. Nick goes on the run when he’s framed for a crime he didn’t commit. Zootopia’s top cop, a self-righteous rabbit, named Lt. Judy Hops, is hot on his tail, but when both become targets of a conspiracy, they’re forced to team up and discover even natural enemies can become best friends.”
